But it occurred after apt-get update - zimbra-mbox-webclient-war updated and then Houston we have a problem. iMac Safari does connect to https, Android does not work, Windows10 does not work...... iMac Safari mobile client and html login does not work (standaard and Ajax do work)

Please help.

Hi there,

Try the solution from lfasci; I use the same version as yours and it worked fine.
